When I tighten the 8P8C, the clip applies too much pressure, causing it to slip from the socket. Sometimes bending it doesn’t help because it’s already significantly bent. I purchased a Monoprice cat6 8P8C, which suggests they might be of decent quality. The crimping tool I bought on AliExpress seems inexpensive, so that could be the issue. I’m curious if a better-quality crimper should work without needing such force, even for just one use. I might be using too much pressure, but I wasn’t sure. This tool is a Vention RJ45 Crimping Tool, part of their RJ45 Network Cutting Tools line. See the before and after here: https://imgur.com/a/0IWVBxe
It's a subpar crimping device. The issue isn't just the function, but its construction – it applies force at an angle, making contacts near the tool tip experience greater pressure while also exerting stress on the plastic barriers between them. Ideally, a quality crimper distributes uniform pressure across all pins. Some options mimic this design: one example is from Digikey (link provided). Another similar model appears on Amazon (links shared). A more straightforward version without ratcheting and basic insulation removal still maintains even contact pressure, as seen in this product: Gaobige Crimping Tool.
Great feedback on the value you found. For hobby use it worked fine, but once you dive deeper, better options become important. The tools from this brand have shown solid performance at a reasonable price.
